OK,
so breifly ill list my issue :

MY FISH DIE!!!!

I have a 2 yo established ( we did move 7 months ago and re-set it all then ) FO tank.
With sump i run around 70gal.
No live rock,
I have : 15 gal sump with remora skimmer, chaeto, and filter pads, i removed the bio balls 2 weeks ago.

Ever since i got the tank the only thing i can make live are my hermits..

I get fish, chromis and or a goby and they do well a week then croke!!
I feed every other day - and only what they will consume.
The tank levels read normal on all but nitrates and thats well under 30ppm.
Im told the chaeto will help with that .

WHAT CAN POSSIBLY BE WRONG??? what should i check? do ?? try??
 
Can you please post all your tank water and did you add or change anything to the tank lately?
 
andrew-

Todays Tests :

5:30pm pst

SG : 1.024
Ph : 8.0
Temp : 76
Ammonia : 0ppm
Nitrites : 0ppm
Nitrates : 20-25ppm

I havent changed anything other than the bio balls being removed 2 weeks ago to make room for the chaeto in the sump.
I also notice some new green hairish algae in small spots ( maybe my photo period it too long or the algae food stuck? ) so im adjusting that ...
I got the last batch of fish on the 21st of Jan. 3 chromis, 1 yellow clown goby.
Today i have 1 chromis left. And my same 8 hermits ( they are almost 2 years old )

Im feeding formula One and VHP
 
Did you by any chance fill the tank using a water hose. Even a new one. We had a local guy do this a few years ago and had the same problem.

When he set up the tank he used a garden hose to fill it then mixed the salt in the tank. No big deal with a new tank as far as mixing the salt in the tank.

Turned out the water hose was the problem. He removed everything cleaned the tank and equipment, and restarted with new sand and rock and 6 weeks later he was keeping whatever he wanted fish wise.

This was the advise of the lfs owner and it worked, he is now a happy reefer.

i removed the bio balls 2 weeks ago.

I think this is your problem, bio-balls need to be removed gradually, and let the bacteria have time to transfer onto other media (LR's or sand bed). Do so eruptivity will cause an ammonia spike and another new tank cycling. Without BB's, I think you should also upgrade your skimmer to something more powerful (like Euro-Reef or ASM), since the skimmer is you only active filter in the entire system, you need something that can extract a lot of skimmate.

Your nitrate is fine, my fish swim in water with NO3 as high as 60ppm without any problem.
 
Did you remove all the bio-balls? That should pretty much removed the biological filtering for your tank as it was described above.

Are your test kits detecting Ammonia and Nitrite levels as 0 PPM?
 
yes -- ALL bioballs were removed ( at the advise of my local fs store owner, kevin from aquatic dreams ) ... the chaeto was placed that day.

Can i keep some bio balls - in with the chaeto?!!! in sump i mean?!

the ammonia and nitrites read 0 on my tests - yes.
im using both - seachem and saltmaster

I didnt fill the tank with a hose- i use RO/DI only from my home, and then bottle

im feeding every other day -
and water changing one a month 30%

The more i read the more confused i am.. LOL make since?
 
If the bio-balls have been dry for a couple of weeks they wouldn't be much use in solving the current problem. If your not having problems with ammonia and nitrite it doesn't sound like your tank is cycling.

I haven't used refugiums so I can't comment on the advice given to you in that regard. My experience in FO systems is with using mechanical devices for filtration (wet/dry, skimmer, canisters, etc...)

When did the fish die? Recently or right after you removed the bio-balls?
 
Never mind about when the fish die, I reread the original post. I see the answer to my question now.

No fish ever lives past a week in the past 2 year, correct?

i thought nitrates in a FO didnt affect it as much?

April,

As for nitrates, well, according to Robert Fenner's The Conscientious Marine Aquarist page 81,

"There is no clear dividing line over which nitrate is absolutely harmful; conditioned fishes and invertebrates have been cultured in water of several hundred - even thousand - ppm. All that can be said without fear of contradiction is that lower numbers are better."

Before everyone freaks out, the keys here are conditioned and lower is better.

I doubt it's the nitrates.

High nitrates would kill the inverts before they would kill fish IMO.

Are all your fish coming from the same store?

Maybe they are selling fish caught with cyanide?

That's just a quess, but try somewhere else and acclimate very slowly (two hours).

See if you can keep a Damsel alive....
 
aquaman -

Yes ( the most recent fishes ) they have been from the same store. Im thinking of trying liveaquaria.com again. I didnt have this dying issue before we moved.
And my tank was reading the same.

I have 1 chromis now. LOL
and still 8 hermits. the inverts to great?! weird huh?

Maybe ill just give it more time and see what happens, Im happy with my remora, and my sump, and my filtering capabilities i just dont get why all the sudden this issue arizes.

Maybe im adding too many fish at once ( i bought 4 last time ) i am using drip but only for 45 minutes.. ill slow it down a bit next time to aclimate.
 
Could it be that there is something in the new water supply has something that your RO/DI isn't removing sufficiently. Just trying to help

It was ammonia spike, but that was two weeks ago. You did not do the ammonia test immediately after the BB's were removed, did you? Even small amount of ammonia for a short period of time is bad for fish, these spikes can disappear the next day as nitrification bacteria starts to convert it into nitrite/nitrate. If there was a spike two weeks ago, it won't be detectable now.

You also add cheato, but chaeto don't do much for ammonia, they mainly remove nitrate, that's all. One question, did you put DSB in the refugium? DSB adds another protection, it's another filter media for bacteria to grow on and can remove nitrate too.

As I said before, the ammonia was there and is gone now (ammonia=0, nitrite=0), chaeto in place. Go and increase skimming, and you can start to add new fish back, add one every two weeks, do it very slowly, treat it just like a new tank.
 
what is DSB??? i will do whatever i need to?!

I will wait a week and see if this chromis lives still.. retest, water change, and add 1 more..
maybe by the time the year 3000 gets here ill have 10 fish?!
LMBO!!
 
DSB = Deep Sand Bed

By creating a sand bed with a depth of at least 5". You are creating, deep in the sand bed, an anaerobic layers with very little oxygen present. Inside this layer, de-nitrification process will occur and NO3 is further converted into nitrogen.

DSB is optional in a fuge if you have chaeto inside already. If you want to set one up, take some sand from the dsiplay to seed it.
 
Without the live rock I would add the bioballs back. Make sure your filter pads filter the water before they hit the bioballs. You need more filtration then just your skimmer and chaeto IMO. Nitrates don't kill fish. I would suggest taking your water to a LFS and having it checked for ammonia. Your test kit may be bad. I would almost guarentee that you had an ammonia spike after removing the bioballs. Also when you add your top off water do you buffer it? That ro water can be harsh and cause your ph to get out of whack.
 
SEAN -

I do not buffer my RODI water after its made, and before i add it to the tank. My ph has been perfect?! should i be doing something?!

My filter pads are the first to be hit with water from the return ... then the chamber below had balls ( that i took out ) then the chamber below that has the chaeto now... it flows to the open area in the sump where the return pump and skimmer sit.
I dont know where or how i would keep sand down there, so i think i will deffinatly add the balls back in.
If im spiking in ammonia ( wich sounds like i am ) why would this do it EVERYTIME i get fish??

Maybe i better just stick to crabs eigh?!
